[French survey about intradermal BCG SSI adverse events in children under 6 years of age].

During April 2006, 579 physicians took part in a survey about intradermal BCG SSI adverse events (AE) in children less than 6 years old, managed by InfoVac France. Since January 2006, 68% physicians (paediatricians: 73% and general practitioners [GP]: 60%) have vaccinated at least one child. The site of injection is mainly the extern side of the shoulder (72%), according to the recommendations. Systematic vaccination is continued by 54% GP and 26% paediatricians. Others indications are: admission in day care center (33%), admission in day care center associated with risk factors (24%), or only risks factors (8%). Half physicians observed AE and 6% of them reported them at pharmacovigilance centers or pharmaceutical company. AE were mainly inflammations or indurations over 1 cm (for 75% of physicians who observed AE), oozing (73%). Abscesses are notified by 54%, ulcers by 39%, lymphadenopathies over 1 cm by 20%, suppurative lymphadenopathies by 3% and keloid scares by 17% of them, several AE may coexist for some children. Our aim is to start a prospective follow-up of BCG-SSI vaccination and its AE; 58% physicians who answered this investigation agreed to participate.

Report of a case of congenital malaria Plasmodium malariae in France.

Congenital malaria (CM) has been considered to be rare, even in malaria-endemic areas but the disease can result in significant neonatal morbidity. Because of its rarity, the disease may go undiagnosed for a prolonged period in a seriously ill infant. We report the first case of Plasmodium malariae CM from a HIV mother. HIV could have facilitated the transfer of erythrocytic persistent P. malariae through the placenta to the fetus.

[Influenza vaccination coverage rate in children with underlying chronic disorders in 7 French pediatric wards].

UNLABELLED: In France, annual influenza vaccination is recommended and free of charge for children with chronic disease (chronic lung, heart or kidney disease, diabetes, haemoglobinopathy, immune deficiency). The national goal is to reach 75% influenza vaccination coverage by 2008, but data on coverage in high risk children are limited. OBJECTIVES: To estimate the influenza vaccination coverage in children with an underlying chronic health condition in the Paris region, during in- or out-patient visit at hospital. METHODS: A multicentre cross-sectional descriptive study was carried out over 2 months before the 2004-2005 flu vaccination campaign in 7 French paediatric hospitals (Paris region). Inclusion criteria for this survey were: children aged 6 months to 18 years, with an underlying chronic disease requiring annual influenza vaccination, with a vaccination card available, so as to check their vaccination status. Reasons for non vaccination were recorded. RESULTS: Data from 239 children were analysed. 56% of patients were males (mean age: 8.1 years). Two patients had 2 separate underlying chronic disorders; 69% had a haemoglobinopathy, 16.3% had a chronic respiratory disease, and 7.5% had diabetes. The influenza vaccination rate for 2003-2004 was 43.7% (haemoglobinopathy: 55.5%; chronic respiratory diseases: 12.8%). This rate increased from 20.4% to 43.7% between 1999 and 2003. Less than 16% of parents remembered having received a voucher for free vaccination from the National Health Insurance Agency. CONCLUSION: Efforts are still needed to achieve the 2008 objectives of 75% coverage.

[Recurrent respiratory tract infections: how should we investigate and treat?].

Recurrent respiratory tract infections are a common reason for visits to primary care practitioners or hospital physicians. They are placed at the junction of several medical specialities: paediatrics, ENT, pneumology, allergology, immunology, infectiology. The great diversity of the laboratory tests requested and on the other hand the proposed treatments, are the consequences of the diversity of the patients encountered and the paucity of the evidence based-medicine studies in this setting. The dilemma is how to identify the child for which recurrent respiratory tract infections are the witness of underlying condition, without performing repeated medical examinations, laboratory tests and treatments for normal children for which immunologic development occurs normally. The essential tools are the history analysis, physical examination and few laboratory tests. The other questions are how to include, for these patients, influenza and pneumococcal vaccines in the immunization program and how to assess the benefit/risk ratio and the cost of surgical treatments. This paper presents the thought of an expert group trying to define the situations where biological tests or treatments are useful.

[Action to be taken when facing one or more cases of whooping-cough].

The evolution of the epidemiology of pertussis, new licensed macrolides and vaccines, new recommendations for vaccination among adolescents and adults need an update of the French guidelines for prevention of the disease around one or grouped cases of the disease. A particular attention should be raised to the diagnosis of whooping cough in adults who are presently the main reservoir of Bordetella pertussis. Whooping cough in adults presents as an unexplained prolonged cough with nocturnal exacerbation witch accounts for most of the contaminations of young infants. A bacteriological confirmation of pertussis should be provided before implementation of preventive measures: culture and PCR are presently the gold standard for the diagnosis of pertussis in infants, children and even adults who have been coughing for less than 20 days. Later on, serology (Elisa, immuno-empreinte) is the only technique available, but cannot be interpreted if the patient has been vaccinated less than one year ago. Infants under three months should be admitted to hospital and every case submitted to respiratory isolation. Eviction from the community should be pronounced within the five first days following the onset of an effective antibiotic treatment. New macrolides should be favoured: clarithromycin for seven days or azithromycin for five days. Household contacts should be given the same prophylactic antibiotic treatment: children and adolescent not correctly immunized, parents of the index case as adults parents of not or not completely immunized infants. The vaccination program of the household should be updated. The same measures should be applied in case of grouped cases (at least two contemporary or consecutive cases in the same area). In that case, the Public Health System doctors should be involved in the investigation and the classification of the cases. The close contacts not or not completely immunized should be prescribed and antibiotic prophylaxis and an update of their vaccination program. Among the occasional contacts, high-risk people only should be treated. In the day care centres an antibiotic prophylaxis should be given to children who have received less than four vaccine shots against pertussis and to the personnel contact to the cases as well. In the schools, the antibiotic prophylaxis should be prescribed to all children of the classroom(s) not completely vaccinated and to the teacher(s) as well. In the boarding schools and institutions with handicapped children, antibiotic prophylaxis could be applied to every member if the pertussis vaccine coverage is at less than 50%. In hospitals, coughing personnel should wear masks and investigations towards pertussis should be performed in people with a more than seven day unexplained cough. Preventive measures should be applied in case of confirmation of pertussis.

[Acute transverse myelitis associated with Mycoplasma pneumoniae infection in an eight year old boy].

Many Mycoplasma pneumoniae extra respiratory infections have already been reported. The authors report the case of an eight year old child, presenting with acute transverse myelitis, with a PCR proven involvement of M. pneumoniae in CSF as well as the presence of specific IgM in blood. Acute transverse myelitis may have many causes, most of the time viral. The mechanisms of neurological involvement in M. pneumoniae infections are still unclear, but several points indicate an immune reaction. Corticotherapy first i.v. then per os has proved to be an efficient treatment for acute myelitis. Antibiotherapy is discussed because of the undocumented mechanisms of neurological involvement related to the mycoplasma.

[Epidemiology of tuberculosis in France].

Tuberculosis remains one of the leading cause of death from infectious disease in the world. Tuberculosis control is one of the Word Health Organisation priority. One third of the population was estimated to be bacillus tuberculosis carrier responsible for 8 million of new tuberculosis cases occurring each year and nearly 2 million deaths. In Europe near 400,000 cases have been declared in 2001 with a west-east gradient in the incidence rate: 11 cases for 100,000 in west european countries, 41 per 100,000 in central european countries and 92 per 100,000 in east european countries. The number of tuberculosis cases decreased in France with an average annual decline of 7.5% between 1972 and 1988. This trend discontinued in 1989. Between 1991 and 1993 the number of reported tuberculosis increased. This excess of cases is attributable partly to HIV infection, but also to worsening in socio-economic conditions. From 1993 to 1997 the number of cases decreases again and the incidence rate is about 11 p. 100,000 and remains stable. In 2002, 6322 cases have been declared in France. There are important geographic differences. The Ile de France region has the highest incidence rate: 27.1 per 100,000. The rates of the other regions are much lower. The infection risk is different according to age, sex and nationality. People over 75 are one of the most affected age group. Children under 15 years of age represent 4.3% of cases with half of these cases before 5 years of age. As in adult, incidence rate of tuberculosis is 11 fold higher in migrants children than in french children. Less than 10 cases of tuberculous meningitis are reported annually under 15 years of age. Since 2003, mandatory notification includes tuberculous infection for children under 15 years of age. Data recorded in mandatory notification might be useful to improve tuberculosis control in France.

[Congenital malaria as a result of Plasmodium malariae in an infant born to a HIV-seropositive woman].

Congenital malaria is uncommon in France. The purpose of this report is to describe a case involving a six-week-old infant who was hospitalized with fever, hepatosplenomegaly, anemia and thrombopenia. Thick and thin blood smears were positive for Plasmodium malariae. The infant responded favorably to chloroquine. Based on this experience, we performed a search of the literature to find case reports on congenital malaria in France and compare clinical and epidemiologic data with series reported in the United States and from endemic areas. The placenta appears to provide an effective barrier against Plasmodium since infection is much more common than disease. The delay for onset of clinical symptoms is longer in temperate zones than in endemic areas. The type of parasite could account for this difference since African congenital malaria are due to Plasmodium falciparum while most cases described in the United States are due to Plasmodium vivax. We also discuss the possible implications of coinfection by HIV in the mother.

[Epidemiology of nosocomial infections in neonates].

Epidemiology of nosocomial infections in neonates has to be described according to our definitions (early onset GBS diseases excluded) and according to levels of care. Nosocomial risk exists in maternity departments (3% in postnatal beds), incidence rates are 7.5-12.7% or 1.3-8.5 per 1000 days in neonatal care units and 14.2% or 11.7 per 1000 days in neonatal intensive care units (NICU). Gram-positive cocci bloodstream infections are the most common nosocomial infections in NICU but viral gastroenteritis are more frequent in neonatal care units. Risk factors are low birthweight, small gestational age and intravascular catheter in NICU, and for viral nosocomial infections, visits and winter outbreaks.

[Clinical effectiveness of seven-valent pneumococcal conjugate vaccine (Prevenar) against invasive pneumococcal diseases: prospects for children in France].

A seven-valent pneumococcal polysaccharide-CRM197 carrier protein conjugate vaccine (PNC7V; Prevenar, Wyeth, Paris) targets the serotypes (belonging to serogroups 14, 6, 19, 18, 23, 9, and 4) most often responsible for invasive pneumococcal disease (IPD) among children. A randomized, controlled, double-masked study among 37,868 children in northern California (Northern California Kaiser Permanente, USA) provided a per protocol vaccine efficacy value of 97.7% against invasive pediatric IPD due to the vaccine serotypes. The PNC7V vaccine was registered by the European Agency for the Evaluation of Medicinal Products (EMEA) in October 2000; a favorable "Community Marketing Decision" under the Centralized Procedure was granted in February 2001. PNC7V was recommended for most infants by the Conseil Supérieur d'Hygiène Publique de France in March 2002, on the advice of the Comité Technique des Vaccinations, as S. pneumoniae in children less than 2 years of age is the primary cause of bacterial meningitis and of mortality associated with community-acquired bacterial infections. The theoretical coverage of the vaccine towards pneumococcal invasive disease in France is about 80%, which represents one of the best serotype coverage estimates in Europe, and vaccines serotypes account for 90% of penicillin-nonsusceptible strains. Distinctive characteristics in France in terms of epidemiology, life style, and therapeutic attitudes justify a precise follow up of the consequences of the vaccination on a national level during the coming years. Hence, surveillance programs have been established: (i) to ascertain the future impact of large-scale PNC7V vaccination on invasive pneumococcal disease incidence, (ii) to follow the evolution of carriage and ecology of the pneumococcus, and (iii) to establish an active "vaccinovigilance".

[Symptomatic rickets in adolescents].

Although systematic vitamin D supplementation in adolescents remains debated, rickets is nevertheless a well recognized pathology in this age group. Adolescence is an at-risk period because of rapid growth, insufficient calcium intake and/or vitamin D status. Surveys have shown that calcium intake is insufficient (< 1000 mg a day) in 45% of boys and 71% of girls and that vitamin D status is deficient (25-OH-D < 10 ng/ml). The aims of the study carried out by the Calcium Group of the Société Française de Pédiatrie, were to evaluate the frequency of rickets, and to define the criteria for the adolescent population at risk. Forty-one adolescents with rickets were hospitalized between 1985 and 2000. Most of the cases were from the Northern France: 20 from Paris and suburbs, eight from the North-West, four from the North, four from the North-East; five were from the Center of France. The mean age was 13 years and two months for the 28 girls, and 14 years and four months for the 13 boys. Eighty per cent of the adolescents were from immigrant families (33/41): 15 were from sub-Saharan Africa, ten from North Africa, six from Pakistan and two from Turkey. Two thirds of the adolescents were hospitalized in the 2nd quarter of the year. Some adolescents suffered from lower limb pain, 16 had deformations of lower limbs, particularly genu valgum, associated with pain; seven others had either muscle spasms (4), tetany (3). Serum calcium level was low (average 1.84 mmol/l: [1.1-2.5]), and serum 25-OH D level was extremely low. Radiographic characteristics observed were metaphyseal strips on the knees, with condensed edges at times, with the presence of bone demineralization. The treatment combined calcium and vitamin D, and was often administered intravenously when a hypocalcemia was detected. Rickets is not frequent in adolescents, but nonetheless this pathology is not exceptional, and the number of cases is probably under-estimated. Rickets affects immigrant adolescents in particular but nevertheless could also present a certain risk period for the general population.

[Acute bartholinitis caused by Pseudomonas aeruginosa in an 18-month-old infant].

UNLABELLED: Acute bartholinitis is a disease usually seen in women in the period of genital activity. Its occurence in a prepubertal child is an extremely rare event. CASE REPORT: We describe the case of a 18-month-old infant presenting a Bartholin's gland abces caused by Pseudomonas Aeruginosa with a resolutive evolution after antibiotherapy and surgical drainage. CONCLUSION: Diagnosis of Bartholinitis should be considered in any female infant with a labial enlargement.

[Paediatric intervertebral calcifications: two cases report and review of the literature].

UNLABELLED: Discal calcification in childhood is rare. Calcifications are occasionally discovered during routine examinations. Generally, the calcification process is confined to the nucleus pulposus of the intervertebral disc. CASES REPORT: We describe the cases of two children, five and seven years old who presented with acute low back pain. The patients underwent a CT scan, which demonstrated a posterolateral calcified disc hernia. DISCUSSION: Only a few cases with evidence of calcification of the herniated portion of the disc have been previously described. The clinical picture is composed of pain and functional limitation. The radiographic picture consists of the association of morphological and structural alterations of vertebral bodies adjacent to one or more disc calcifications usually centrally sited, sometimes associated with anterior or posterior herniations. The surgical decompression of the nerve root could be necessary.

Childhood tuberculosis in a low-income Paris suburb: lessons from a resurgence brought under control.

SETTING: Few series of paediatric tuberculosis (TB) have been reported in the last 20 years. OBJECTIVE: To describe diagnostic and treatment practices in children with TB living in Seine-Saint-Denis, a low-income Paris suburb. METHODS: Local TB incidence in 1998 was 34.2/100,000 overall and 10.2/100,000 in children. Between September 1996 and December 1997, the hospitals and prevention units serving the area's paediatric population were sent questionnaires to identify TB cases in children aged under 15 living in Seine-Saint-Denis and treated with at least one anti-tuberculosis drug. RESULTS: Of 92 cases identified, 60 (65%) had been diagnosed during contact tracing; for 52 patients (60%), the index case had been found. The reason for anti-tuberculosis treatment was active TB in 26 (28.3%), latent TB in 46 (50%), and prophylaxis in 20 (21.8%). Forty per cent (37/92) of the patients were aged under 5. Only 15 of the 35 notified cases met the criteria for mandatory notification (at least three anti-tuberculosis drugs). CONCLUSION: TB remains a public health problem in Seine-Saint-Denis. The high proportion of cases identified by contact tracing attests to the efficacy of the local contact-tracing programme. The criteria for mandatory notification in France were too restrictive to ensure effective surveillance of childhood TB. Since 2002, notification has included cases of tuberculous infection in children.

Multicentre study of the molecular epidemiology, serotypes and antimicrobial susceptibility patterns of invasive Streptococcus pneumoniae invasive isolated from children in the Ille de France area.

Between January 1997 and April 2002, 73 consecutive invasive strains of Streptococcus pneumoniae were isolated from children under 16 years of age in four hospitals in suburban Paris. Their genetic diversity was investigated by serotyping and analysis of pulsed-field gel electrophoresis restriction patterns. Antibiotic susceptibility patterns were analysed by disk susceptibility testing and determination of minimal inhibitory concentrations. The genetic basis of macrolide resistance was investigated by polymerase chain reaction. Studies of penicillin and vancomycin tolerance were performed for each strain. Despite the high prevalence (45.2%) of penicillin-nonsusceptible Streptococcus pneumoniae, resistance to amoxicillin (1.4%) was rare, and no strain was resistant to cefotaxime. Overall, 4.1% of pneumococcal strains were resistant to penicillin. Penicillin or vancomycin tolerance was not detected in any of the 73 strains studied. Of the erythromycin-resistant strains (48%), all but one carried the ermB gene. No strains showing a decreased susceptibility to ciprofloxacin (MIC, >4 mg/l) or overexpressing an efflux pump inhibited by reserpine were isolated. The serotypes found, in order of frequency, were as follows: 18C, 14, 6B, 19F, 19A, 9V, 23F, 1, 7F, 9A, 38. Strains of penicillin-nonsusceptible Streptococcus pneumoniae belonged predominantly to serotypes 14, 6B, 9V, 9A, 23F, 19F and 19A. The seven-valent conjugated vaccine covered 85.5% of the serogroups isolated in children under 2 years of age and 65.6% of the serogroups identified in children over 2 years of age. The genetic analysis showed a high identity for some serotypes, such as 14/9V, 6B and 23F. The use of the seven-valent conjugated vaccine is a critical measure to prevent invasive pneumococci infections in children in the Ille de France area.
